RFC5297 · Synthetic Initialization Vector (SIV) Authenticated Encryption Using the Advanced Encryption Standard (AES)
Synthetic Initialization Vector (SIV) Authenticated Encryption Using the Advanced Encryption Standard (AES)
This memo describes SIV (Synthetic Initialization Vector), a block cipher mode of operation. SIV takes a key, a plaintext, and multiple variable-length octet strings that will be authenticated but not encrypted. It produces a ciphertext having the same length as the plaintext and a synthetic initialization vector. Depending on how it is used, SIV achieves either the goal of deterministic authenticated encryption or the goal of nonce-based, misuse-resistant authenticated encryption. This memo provides information for the Internet community.
